That tester looks cool. I remember seeing one at an authorized Nintendo repair place when I was a lot younger. I brought my Gameboy in for a screen replacement and they were using a unit similar to that one to run diagostics on a SNES that was brought in for some type of service. They charged like $25 in 1994 to run the tests I remember.
Ohhh no way! I always thought these were just owned by Nintendo repair guys. You would send your broken stuff to their outlets and they would diagnose it / send it back. These units do look pretty user friendly, so that would make sense. I didn't think these were out in the open for people to see, thanks for sharing.
Its interesting, because each test cart has a slightly different animation set to test. I'm surprised it needs such a big housing, since it does nearly the same thing as the smaller test carts I have.
That's a good point. Because in addition to this 32X looking thing, there were other test SNES cartridges. Only one i can think of top of my head is the burn in cartridge, which is fairly common to find. and not expensive. The ones you have, are they the 5 or so yellow NES carts or a snes cart test cart?
